.T 1J/Z whom, it ntmy concern,.-

Beit known that I, CLARENCE L. Tar Lon, of Alliance, in the county of Stark and State of Ohio, have invented certain new and useful Improvements in I-Iydraulic Cranes; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to an improvement in hydraulic cranes adapted more particularly for use in forge-shops, the object being to so mount the main hoist-cylinder that it will be free to oscillate in any direction, and hence ca able of yielding or giving in the event the cy inder, piston, or load carried by the piston should come in contactl with an object, and also permit the cylinder to give to accommod ate itself to the lag of the load.

vWith these and other ends in view my invention consists in the parts and combinations of parts, as will be more fully explained, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a view in side elevation of a section of a bridge showing my improvement thereon.

' Fig. 2 is a view in transverse section through the bridge, trolley, and main cylinder. Fig. 3 is an enlarged view through bridge, trolley, cylinder, and cylinder-mounting, part of the trolley and cylinder-moiniting being in section. Fig. 4 is a view taken at right angles to Fig. 3, and Fig. 5 is a view in section on the line A A of Fig. 3.

1 re resents an overhead traveling bridge propelled lengthwise its supporting-tracklhis motor is geared up to shaft 4, running lengtlnvise the bridgegirders, and the shaft is provided at its ends with gear-wheels which mesh with larger' gears 5 on shafts 6. These shafts 6 carry smaller gears 7, which mesh with the larger gears S on the axles of the track-wheels 9, the central flanges of which travel between the rails of track 2.

Mounted on rails 10, carried on to of the bridge-girders, is the traveling trolley 11. This trolley is a hollow casting having an open center, the sides` or walls of which opening diverge downwardly, so as to permit the hoist-cylinder 12 to swing freely without colliding with the walls of the trolley.

Secured on top of the trolley and onopposite sides .of the opening in the center thereof and 1n recesses or seats 13 formed therefor' are the bearings 14, which latten are provided with teeth 15 near their outer edges and are plane and fiat at their innery edges. Mounted on these bearings 14 is the rectangular rocking frame 16, provided with bearings 1.7, which latter rest on and engage These-bearf ings have plane surfaces 18 and toothed surthe bearings 14 on the trolley.

faces -19, corresponding to the plane and ss.` 'i

toothed surfaces of bearings 13, and their'- lower bearing-faces are formed in the arc of a'v circle to form rockers, the teeth on the two bearings preventing any creeping movement of the frame 16 on the trolley, lateral displacement being prevented bythe seats 13,-

which also receive the contacting edge of the upper bearings 17, as clearly shown in Fig. 3. This rocking frame 16 is open at its center and is provided on its upper face with the parallel bearings 19, which latter are-located at right angles to the bearings 17 and onopposite sides of the central opening in roeking frame 16. These bearings 19a are-flat and are toothed at their. outer edges and form seats for the rocking bearings 20, carried by the rocking yoke 21 The bearings 2() are curved 1n the arc of a circle and areprovided with plane surfaces to engage theorf plane surfaces of bearings 19a and with toothed portions to engage the. toothed tions of bearings 19. The intermes ing teeth of the bearings 19a and rocker-bearings 20 prevent any creeping of the yoke on the frame in the direction of movement of the yoke, while the engagement of the guides 21, formed on opposite sides of the cylinder,v (see Figs. 4 and 5,) prevent any lateral movement of the yoke. This yoke is provided with a central circular opening to receive the head being seated on the annular shoulder 23 of the yoke. The cylinder is therefore head 22 of cylinder 12, the upper end of the suspended from the yoke, and asv the yoke Y has a rockin" motion on the rocking frame and the latter a rocking motion on the troll* ley at `-'ght angles to the rocking motion'of the `,oke the suspended cylinder is free to sV ing in any direction, limited only in its iovements by the size of the opening in the trolley. p Y 'I Located Within the cylinder l2 is the piston 24, the rod 25 of which passes through the lower end of cylinder and carries at its lower end the bracket 26, in which sheave 27 is mounted. This sheave is designed to carry an endless chain, which forms a supporting-loop for the ingot or forging or tool employed for manipulating the forging. Secured to or formed integral with the yoke 21 is the laterally-projecting platform 28, which carries an electric motor 29. The armatureshaft of this motor carries a pinion 30, which latter meshes with the gear-wheel 31, secured on the upper end of shaft 32. Shaft 32 passes through a bearing in the head of the cylinder 12 and through piston 24 and iston-rod 25, as shown in Fig. 2, and is pro- -vided at its lower end with a worm 33, which meshes With Worm-wheel 34, mounted in a bearing carried by bracket 26. This Worm- Wheel 34 is fixed to a gear-Wheel, which latter meshes with a gear wheel or teeth on sheave 27. It will thus be seen that by starting the motor 29 shaft 32 Will be rotated and by means of the gearing described rotate the sheave 27 and the endless chain carried by the latter. The cylinder 12 is connected by a system of jointed pipes 35 with an accumulator or other -source of Water under compression, and by admitting water under piston 24 the piston and its load Will be elevated and by permitting the water under the piston to escape the load will be lowered. If desired, the bracket 26, carrying sheave 27, may be mounted on roller-bearings, thus permitting the bracket carrying the sheave to be turned on the piston-rod. With this arrangement the load may be carried to any art of the shop covered by the movements of thebridge and trolley and may be raised, lowered, rotated, and turned so as to present any and all parts of the forging to the action of the hammer, and as the cylinder is connected to the trolley by a universal joint, which permits free swinging movement of the cylinder, the latter' will give when the load collides with any other object and will give under the lagging movement of the load. It is evident that many slight changes might be resorted to without departing from the spirit and scope of my invention. Hence I would have it understood that I do not wish to confine myself to the exact construction of parts herein shown and described; but,

Having fully described my invention, what I claim as new, and desire to secure by Letters Iatent, is-
